About Tunnel Construction

There are more than 6,000,000 km of highways and 240,000 km of railway tracks across North America. Of this maze of concrete and rail you're going to run into a mountain here and a river there. Tunnel construction provides routes for vehicles and trains to find there way though these obstacles.

3 Basic Steps to Tunnel Construction

Excavation: Digging through the earth using one of many different tunnel construction methods

Support: The support of any unstable ground while digging is necessary especially in underground tunnels. Beams, masonry bricks or Shotcrete can be used

Tunnel Lining: Final touches for tunnel construction such as roads/tracks and lights are added once the tunnel is structurally sound

Channel Tunnel Building

Channel tunnel construction is particularly tricky. In traditional methods water must be held back while the tunnel construction is taking place. However, prefabricated tunnel segments can be floated into position, sunk and then attached to other sections.

Underground Tunnels

Underground tunnels also provide routes for water, sewage, power and communication lines. Underground tunnels can also be used for subways and also for traffic to travel under water. Underground tunnels are very difficult to build and require precise engineering. .

Tunnel Rehabilitation

Tunnel rehabilitation of underground tunnels has been made easier and faster with the introduction of Steelfiber Shotcrete. Using Steelfiber Shotcrete for tunnel construction or rehabilitation removes the need for time consuming rebar or mesh to be installed.

Tunnel Construction

Using SUPERSEAL Tunnel Drainage or Dimpled Mesh as a separating layer between the outer and inner shells of a tunnel, offers design engineers numerous benefits for underground tunnels and general tunnel construction. Just some of the tunnel construction benefits are:
